I'm trying to make a slider with this tutorial and it works very good. But when I try to get the image url from JSON with volley this url does not work. I want to convert the string to url, but my code is not working.
img1 = obj.getString("image_1");
URL myURL1 = new URL(img1);
Add app/gradle.app as a dependencies
compile 'com.google.code.gson:gson:2.6.2'
Now you need to create a Object.class according to your Json object. And all key names should same as your Object.class
Eg: Json object:
{
"id": 1,
"message": "This is example"
"url": "http://www.jsoneditoronline.org/"
}
Class object:
public class ExampleObject {
public long id;
public String message;
public String url;
}
Then in your Activity.java:
//jsonObj is your JSON object
ExampleObject obj = new Gson().fromJson(jsonObj, ExampleObject.class);
Now all the values are saved into your Object class.
If you want to load the url of the image retrieved in an imageview you can pass the string to an image processing library, for exemple Glide. Here's a good tutorial on how to set it up and use it: https://futurestud.io/tutorials/glide-getting-started.
The Android SDK contains a very useful Uri class. It exposes a Builder that can be used for property URL building (instead of string concatenation, that you are using). It also has a Uri.parse() method, that can create an instance from a String.
